CLAMP FOR RETORT-MOUTHPIECES.

SPECIFICATION forming part of Letters Patent No. 706,642, dated August12, 1902.

Application filed September 21, 1901- Serial No. 76,124. (No model.)

To ml], whom, it may concern:

Be it known that I, JOHN C. DODS, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Clamps forRetort-lVIouthpieces, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

Figure I is a perspective view of my improved clamp. Fig. II is avertical sectional view of the end of a retort with the mouthpiecesecured thereto by my improved clamps. Fig. III is a verticalsectional'vie'w taken on line III III, Fig. II.

1 indicates the body of the clamp, which is preferably of rectangularshape in cross-section. One 'end of the clamp is bent at a right angleto the body to form the hook 2. The opposite end of the clampis beveled,as indicated at 3.

5 indicates the furnace-wall, 6 the retort,

and 7 the retort-mouthpiece. This monthpiece is usually of'castmetal'conformingin shape to the cross-sectional shape of the retort andis provided on its inner edge with a flange 8, that abuts against theend'of the re Formed in the face of the retort adjanotches or recesses9, which receive the hooks or laterally-bent ends 2 of the clamps, theouter beveled ends of said clamps extending beyond the end of theretort. The clamps Passing through a threaded aperture in the beveledend of the clamp at,

laid with the retort located therein- The clamps are laid against theretort,with the hooks located in the notches or recesses 9 in theretort, and when so placed the beveled forward ends of the clampsextendbeyond the outer end of the retort and also beyond the outer face of thefurnace-wall. At this time the screws 4 may be positioned in the outeror forward ends of the clamps, or they may be inserted after the clampsare all in place. When the mouthpiece 7 is to be applied to the retort,the screws at are in receded position, so as to permit the applicationof the mouthpiece within the forward ends of the clamps and againsttheouter end of the retort. After the mouthpiece has been placed againstthe retort the screws are moved inwardly. in the clamps, so as tobearagainst the flange 8 of the mouthpiece at an angle thereto and forcesaid flange inwardly, carrying it tightly to the retort and producing aclose joint between the parts.

I claim as my invention 1 1. In a clamp for retort-mouthpieces, thcombination of a body having a straight outer end, a hook at its innerend and a screw movably seated in its outer end at an angle' thereto,substantially asdescribed.

2. In a clamp for retort-mouthpieces, the combination of a body'having ahook at its inner end, and having a straight beveled forward end, and ascrew passing through said forward endat an'angle to the body of theclamp, substantially as described.

3. In a clamp for retort-mouthpieces, the combination of a body having ahook at its inner end, and having a beveled forward end and a screwpassing throughsaid beveled portion perpendicular thereto, whereby saidscrew receives a firm seat in said body.
